Research on optical properties of perovskite-type LaSrFeO4

摘要:

采用固相反应法制备了LaSrFeO4钙钛矿材料，并且在较大的频率范围内测量了其反射率，然后利用Kramers-Kronig关系(K-K关系)计算了LaSrFeO4的光学参数，即折射率和介电常数．在得到光学参数的基础上，计算了LaSrFeO4的电导率，计算结果与其他课题组公开报道的结果符合的很好．

Abstract:

LaSrFeO4 perovskite material was prepared by using solid-state reaction method， and its reflectivity was measured in a larger frequency range. Then the optical parameters of LaSrFeO4， namely the refractive index and dielectric constant， were calculated by Kramers-Kronig relationship （K-K relationship）. Based on the optical parameters， the conductivity of LaSrFeO4 is calculated， and the calculated results are in good agreement with the results reported by other research groups.
